# Overview

An ingredient can be text, image, or video. You reference it with an `@` tag inside prompts and template copy. Examples include `@Actor`, `@Product`, `@Hook`, `@Body_Problem`, `@CTA`, and `@Broll_Demo`.

Ingredients make projects easier to change. Instead of rewriting every scene when the hook changes, update `@Hook`. Instead of rebuilding a template for every product, swap `@Product`. This is the foundation of remixing, cloning, templates, and ad variations.

Use ingredients for values that are repeated, swappable, brand-specific, or likely to become test variables.
